Quantities of rubber in the form of used waste tires are often dumped and discarded that often lead to environmental problems and unhygienic conditions. This research is undertaken to explore the possibility of using the rubber shredded to the sizes of fine aggregates that could be used as a replacement of normal aggregates in concrete.

In order to calculate the concentration of the analyte, a calibration curve should be constructed, based on the absorbance measurement of at least four standards of known concentration in the appropriate range. It is important to mention, that it is not recommendable to extrapolate over the range of the calibration curve

The solar cells manufactured at present are low in the efficiency and very expensive if they have to be used to generate electricity on a large scale. We are interested in using the valuable features of nanotechnology so that we can manufacture efficient and cheaper solar cells in the large quantities

The main aim of the research was to come up with lightweight materials that can be used to make effective breaking systems and contribute to fuel efficiency. The objective was to investigate the thermal heating, wear and friction characteristic of Titanium alloys in different forms compare the outcome with cast iron under similar treatment

This paper tells that Hydrogen bonding is essential in three-dimensional structures adopted by proteins and nucleic bases. The bonding help forms the matter into the specific shape to determine its molecule's physiological or biochemical role. The double helical structure of DNA is exhibited by hydrogen bonding in the base pairs to network with complementary strands in a replicated manner.

This is the process, which integrates carbon dioxide to organic carbon sugars during photosynthesis. It can also use just the carbon dioxide form of carbon, not bicarbonate or carbonic acid. A cadmium-carrying carbonic anhydrase was discovered to be articulated in marine diatoms during zinc restriction. In the open ocean, this enzyme is in low concentrations to the extent that it can restrict the development of phytoplankton such as diatoms. Therefore, a carbonic anhydrase utilizing a diverse

Cytochrome a3-CuB complex receives two electrons from two cytochrome c molecules, forming Cu1+ and Fe2+ (Hanikenne, Merchant, & Hamel). Water is lost in the process through protonation of the hydroxide molecule. Oxygen is also reduced by electron from the Fe2+ cytochrome complex. This complex is converted to the oxo compound Fe4+=O:This compound, after a series of reactions is ultimately reduced from Fe4+=O to Fe3+; in the process the O atom gains a proton forming oxygen. The overall reaction

Construction of the building ended in nineteen sixty-three. The external form of the building reflects the internal functions making it one of the most conspicuous and respected building in the world (Best & Martin, 2006). James Stirling did a lot of work in Leicester school of engineering from nineteen sixty to nineteen sixty-three. He constructed various forms that reflected internal operations of the building representing the liveliest way of presenting technology. Undertaking a structural

However, these uses have recently reduced due to environmental concerns about cumulative lead poisoning. Presently, Pb is used in storage batteries , paints, pigments and colored inks as shielding from radiation, e., in x-ray rooms and nuclear reactors. Lead is also used as cable covering, as ammunition, as electrodes, in solder and roofing material.(Martiez , Nagae , Zaia , & Zaia 2004).The fate and behavior of Pb in the environment is quite complex because of the many compounds of Pb and

It was then determined that indeed starch granules are very suitable stabilizers for food grade pickering emulsions. This is because the initial encapsulation efficiency was over 98% after the emulsification production. It remained that way and in some instances the encapsulation stability went over 90%.Encapsulation often involves the incorporation of good ingredients in enzymes, cells as well as other materials in small capsules. In fact, the application of this technique has been pivotal as

Magnetic methods are based on detection of the magnetic properties of the rocks. Detected difference provide the possibility to suggest the presence of desired materials. Seismic methods are based on creation artificial shock and detection the time necessary for the vibration impulse to get to the seismic detector. Depending on the obtained results, the conclusion about presence of oil can be made. Electric and radioactive methods are based on the measurement of conductivity and radioactivity

Methane hydrate mostly occurs in the Arctic and coastal regions. However, even though the gas is known to be potential sources of energy, and a potential pollutant, knowledge regarding the formation and the occurrence of the compound are vital. Geologists argue for two processes that contribute to the formation of this unique compound.
